Abstract: Described are molded bodies comprising bond material based on cellulose acetate as a bonding agent and reinforcing natural cellulose fibers or natural cellulose-containing fibers. These components are characterized by the fact that the cellulose acetate has a degree of substitution (DS) of approximately 1.2 to 2.7 and the molded bodies have a Vicat temperature of at least approximately 160.degree. C. and the ratio of the weight of cellulose acetate to the natural cellulose fibers or natural cellulose-containing fibers is approximately 10:90-90:10. These molded bodies are produced by mixing cellulose acetate with the natural cellulose fibers or the natural cellulose-containing fibers in a ratio by weight of approximately 90:10-10:90, in particular 15:85-85:15, in the total moisture content is adjusted to at least approximately 3% by weight, with respect to the total amount of the cellulose acetate in the mixture, and this mixture is molded at a temperature of approximately 220.degree. to 280.degree. C.
